POWER TRANSNHSSION.

Specification of Letters Patent.

Patented Feb. 12. 1907 Applipation filed September 11, 1905. Seri l No- 278,062.

To all whom it may concern.-

Be it known that I, Mortars Mosltownz, a citizen of the United States, and a resident of the borough of Brooklyn, county of Kings. city and State of New York, have invented certain new and useful Improvements in Power Transmission, of which the following is a specification accompanied by drawings.

This invention relates to improvements in )ower transmission, more particularly to improved means for transmittin power from the axle of a cartruck to a dynamoelectric machine suitably suspended from the truck.

The object of the invention is to obviate the wear upon the axle of the dynamo and the consequent destruction of the armature.

which occurs with the usual power-transmitt-ing mechanism.

The. invention in some respects is an imrovement upon the construction disclosed In United States Patent No. 768.392. granted. to me August 23, 1904.

I haye preferably illustrated the present invention'in connection with the same mode of suspension disclosed in said prior patent, although the invention may be used in any connection in which it is applicable.

Further objects of the invention will hereinafter appear; and to these ends the invention consists of apparatus for'carrying out the above objects embodying the features of construction, combinations of elements,

and arrangement of parts having the eneral mode of operation substantially as iereinafter fully described and claimed in the accompanying s ecification, and shown in the drawingsfin w ich Figure 1 is a side elevation. partlv in section, of the end of a truck for a rai way-car provided witha dynamo driven in accord: ance with this invention. Fig. 2 is a plan view; and Fig. 3 is an end view,partly in section.

Referrin to the drawings, A represents the car-ax e; B, the wheels, running on the rails C. D represents the wheel-guards, and E is the end Slll. These parts of the car may be constructed in the usual manner.

The dynamo F is suspended outside of the end sill of the truck by beams G, secured to the wheel-guardsD, the ends of the beams projecting beyond the end sills E. The dynamo F is cushioned in a vertical direction by suitable cushioning-springs H.

Pivot-bars I are pivoted at J to the angle beams G, while the other ends of said beams bear upon the cushioning-springs .H. The in ner ends of the pivot-bars I may be pivoted to the angle-beams G in any suitable manner in this instance a bearin K being secured to the wheel-guard D, wide a pivotepin L passes through the upright flange of the angle-beam G .and through said bearing The eye or enlarged portion 0 of the bar I is pivoted upon the pin L. Suitable bearings P are provided upon the pivot-bars I for the shaft Q, uJon which the dynamo F is pivoted. The shaft Q, as shown, extends transversely of the truck and asses through the ears'R on the field S of tie dynamo F. The Weight of the dynamo F is therefore transmitted through the shaft Q to the pivotbars I and from thence throught'he cushioning-springs H to the angle-beams G.

The axle A is provided with a suitable drivin pulley T, connected by a belt U with the u ley V. connected to drive the shaftW of tie dynamo in accordance with this invention. Suitable belt-tightening springs X are provided, and downwardly-depending rods Y are secured to the outenends of the angle-beams G, the lower ends of these rods being connected by a cross-rod Z. The field of the dynamo is provided with downwardlydepending lugs or ears o a cross-r0 I), provided with apertures at its ends for the hooked rods c. These hooked rods 0 are provided with screwthreads. The rods 0 are thrust through the apertures d in the rods or bars I) and also through the apertures e in the cross rods or bars Z. The springs X are passed over the ends of the rods 0 and compressed between the crossrods Z and the gravity-nutsf. The tendency of the springs X is therefore to pull the lower portion of the dynamo F away from the caraxle A, and thereby maintain the belt U Preferably a cross-rod g is rovided, connecting two pivot-bars I toget er. Suitable bearings h are provided on the field of the to which is secureddynamo for the shaft W of the dynamo. A cross binding-rod "i is preferably rovided, connecting the two downwardlya epending bars Y.

A frame j, forming one bearing for the dynamo-shaft is suitably connected to the field S, as by means of the bolts k, and u on the outer end of said frame is carried t efpulley V, which is connected todrive the sha t W by means of a dog orspider 0, keyed to the shaft and having arms p loosely in serted in apertures in the body or spokes of whey V. A nut q or other suitable means iolds the dog on the shaft. Any other suitable means may be provided for su'rporting the ulley V on a bearing, separate rom the. sha t \V and for driving the shaft from said pulley without throwing a transverse strain upon the shaft. According to the construction disclosed, which has been found to operate satisfactorily and well, the bearings for the dynamo-shaft are not worn away rapidly and the armature remains true for the life of the same. Any suitable form of bearing may be provided for the pulley Y, as a ballbearing or an oilless hearing, which may be readily renewed whenever desired without removing the armature.

Obviously some features of this invention may be used without others, and the invention may be embodied in widely-varyin; forms.

Therefore, without limiting the invention to the construction shown and described nor emnnerating equivalents, I claim, and desire to secure by Letters Patent, the following:

1. The combination with a car-truck, of. a dynamo suitably supported thereon, a belt operatively connected to drive the dynamo from the car-axle, and means for preventing transverse strain on the armature-shaft.

2. The combination with a car-truck, of a dynamo suitably supported thereon, a belt operatively connected to drive the dynamo from the ear-axle, and means for preventing substantial wear upon the armature-shaft 'or its bearings.

3. The combination with a. car-truck, of a dynamo suitably support-ed thereon, a belt operatively connected to drive the dynamo from the car-axle, and means for preventing irregular 'wear' upon the armature-shaft or its earings caused by transverse strains on the dynamo-shaft.

4. The combination witha' car-truck, of a dynamo supported thereon, a. frame supported adjacent the armature-shaft, a pulley supported thereon, a dog connecting the pulleywith the armature-shaft to drive said shaft from the pulley, and means for driving the shaft from the axle.

5. The combination with a car-truck, of a dynamo suitably supported thereon, a frame connected to the field of the dynamo, a pulley supported thereon, a doe connecting the pulley with the armature shalt to drive said shaft from the pulley, and means for driving the shaft from the axle.

6. The combination with a car-truck, of a dynamo suitably supported thereon, a frame connected to the field of thedynamo, a pulley revolubly supported thereon, operative c011- nections between the pulley and the armature-shaft, and connections for driving the pulley from the axle.

7. The combination with acar-truck, of a dynamo suitably su' oorted thereon, a frame connected to the fie (i of the dynamo, a pulley supported thereon, a dog connecting the pulley with the armature-shaft to drive said shaft from the ulley and belt for driving the shaft from t e axle.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
